Find the exponential Fourier series for this periodic square wave signal with a duty cycle of 50%. The Fourier series allows us to represent any periodic signal as a sum of sinusoids (or complex exponentials), each with its own amplitude and phase. This concept is at the core of signal analysis, communications, and control systems, helping us understand how complex waveforms are built from simpler components. Let’s walk through this example step by step to see how the math translates into the si

Japan uses piezoelectric ceramic tiles to convert electricity into electrical energy. These tiles capture the kinetic energy from your footsteps. When you walk, your weight and movements put pressure on the tiles. The ceramic tile bends slightly, resulting in mechanical stress. The piezoelectric material inside the ceramic tile converts this stress into electrical energy. Each step produces a small amount of electric charge, and millions of steps combined can produce enough electricity to drive
